Environmental governance in the twenty-first century in Bangladesh faces serious challenges in terms of improving service delivery. There are surfeits of laws, rules and regulations as well as institutions to manage and govern the environmental sector. The legal regime is quite comprehensive, yet little attempts have been made so far to iron out the contradictions and duplications among existing rules and regulations. Institutions continue to suffer because of a number of reasons. Coordination among different ministries and other agencies in the governmental and non-governmental sectors is poor. Inter-organizational meetings and other follow-up meetings are not regularly held and usually fail to achieve their intended objectives. Though attempts have been made to involve people at the formulation stage of action plans, seldom people are taken into confidence and consulted with when these plans are implemented. One of the consequences of such a situation is people’s lack of interest in government-sponsored environmental protection programs. The decision-making procedure/situation of different environmental development projects and policies did not follow the holistic or coordinated principles so that post-impacts of works appeared vast and diverse conflicts. This paper tries to search the history of environmental protection of Bangladesh, relevant environmental laws, rules, regulations and projects and major international conventions, treaties, and protocols signed or ratified by Bangladesh as well as investigates the current situation, mechanism and decision making regarding environment in the context of environmental governance, analyzing the problems and also explored the challenges for environmental management in Bangladesh and associated problems and risks of system and finally proposed some core guidelines of effective environmental governance and system management for Bangladesh.  相似文献

Background, aim, and scope  

The occurrence and fate of pharmaceuticals in the aquatic environment is recognized as one of the emerging issues in environmental chemistry and as a matter of public concern. Existing data tend to focus on the concentrations of pharmaceuticals in the aqueous phase, with limited studies on their concentrations in particulate phase such as sediments. Furthermore, current water quality monitoring does not differentiate between soluble and colloidal phases in water samples, hindering our understanding of the bioavailability and bioaccumulation of pharmaceuticals in aquatic organisms. In this study, an investigation was conducted into the concentrations and phase association (soluble, colloidal, suspended particulate matter or SPM) of selected pharmaceuticals (propranolol, sulfamethoxazole, meberverine, thioridazine, carbamazepine, tamoxifen, indomethacine, diclofenac, and meclofenamic acid) in river water, effluents from sewage treatment works (STW), and groundwater in the UK.  相似文献

Poly(l-lactic acid) (PLLA)/poly(caprolactone) (PCL) and two types of organoclay (OMMT) including a fatty amide and ocatdecylamine montmorillonite (FA-MMT and ODA-MMT) were employed to produce polymer nanocomposites by melt blending. Materials were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), elemental analysis, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Mechanical properties were also investigated for these nanocomposites. The nanocomposites showed increasing mechanical properties and thermal stability. XRD results indicated that the materials formed nanocomposites. SEM morphology showed that increasing content of OMMT reduced the domain size of phase separated particles. TEM outcomes have confirmed the intercalated type of nanocomposite. Additionally, a solution casting process has been used to prepare these nanocomposites and characterized to compare these results with the above process.  相似文献
